The three digit number satisfying the requirements is 112.
The three digit number must be greater than or equal to 100 and less than 140.
To have 7 as a factor it must be a multiple of 7
To be even, it must be an even multiple of 7.
The first even multiple of 7 greater than or equal to 100 is: 100 ÷ 7 = 14 r 2 → first even multiple is 16 × 7 = 112
The last even multiples of 7 less than 140 is: 140 ÷ 7 = 20 → last even multiple is 18 × 7 = 126
The sum of its digits must be less than 9:
112 → 1 + 1 + 2 = 4
126 → 1 + 2 + 6 = 9
→ only 112 fits all the criteria.
